Product Description:

The KSM02.1B-061C-35N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a synchronous servomotor, power electronics, and a network interface in one housing, the device supports decentralized axis control close to the load. It is used in packaging, handling, and small-parts assembly cells where precise torque regulation and reduced cabinet wiring are required. Because the drive is mounted directly on the machine, installation time is reduced and motor cable runs remain short.

Electrical power is supplied to the unit through a Hybrid Connector that carries both the DC bus and control signals, simplifying cable routing. The drive accepts a bus voltage of DC 750 V, matching the common DC link used in Rexroth modular automation systems. Heat is removed by natural convection, so the enclosure does not require fans or liquid cooling when mounted in free air. Network traffic for parameterization and real-time motion commands is handled by the Multi-Ethernet interface, permitting direct connection to EtherNet/IP, PROFINET, or SERCOS over Ethernet. The motor section uses size code 061, which identifies the stator diameter and mounting pattern for this unit.

Position feedback is generated by an optical encoder that delivers 128 signal periods per revolution through the Hiperface interface. The single-turn implementation supplies absolute position within one revolution and simplifies homing after startup. The output uses a plain shaft with a shaft seal, which helps prevent lubricant escape when the unit is mounted horizontally. The motor has length C and winding code 35 for the designated torque range, while the performance level is Basic. The module ships without a holding brake, and the unit is design version 1.
